Why do you assume anyone does?
I do not see the point of this.
The Scottsboro Boys were tried by a kangaroo court and all but one sentenced to death. The verdict was appealed, and with the help of the Communist Party, four more were set free. One was sentenced to death, but the sentence was not carried out. One was killed by a prison guard.
Freddy Grey was arrested on a very minor charge, and never tried. Asa result of his arrest he is now dead.
He did not get any help from the Communist Party, though.
